|Numerical Relativity simulation of Binary Black Holes by Campanelli et al, 2006.|
Near black holes not only have gravity that is so extreme as to generate observable gravitational radiation, but also highly-relativistic gas flows around them can produce powerful electromagnetic signals as the gas is pulled by extreme gravitational forces, and it is believed to be responsible of the launching of the powerful observed jets across the entire universe.

This talk will review some of the new developments in the field of numerical relativity, and relativistic astrophysics that allow us to successfully simulate and visualize the innermost workings of these violent astrophysical phenomena. More images and material can be found in these links:

|Dr. Manuela Campanelli|
Dr. Campanelli has an extensive research experience on Einstein’s theory of General Relativity, astrophysics of black holes and gravitational waves. She is known for groundbreaking work on numerical simulations of binary black hole space times and for explorations of physical effects such as “super kicks” and spin-driven orbital dynamics.
In 2005, she was the lead author of a work that produced a breakthrough on binary black hole simulations. In 2007, she discovered that supermassive black holes can be ejected from most galaxies at speeds of up to 4000km/s. Her more current research focuses on computer simulations of merging supermassive black holes, and on magnetohydrodynamics simulations of their accretion disk and jet dynamics, in connection with both gravitational-wave and electromagnetic observations. She also participates in the LIGO scientific collaboration. The search for gravitational waves from binary black holes and binary neutron stars moved forward in September with the first observing run of the upgraded laser interferometer, Advanced LIGO gravitational wave detectors.
Dr. Campanelli’s research include numerous publications and invited presentations and reviews papers. One of her papers was recently highlighted by the APS as one of the landmark papers of the century on the subject of general relativity, starting with a contribution from Einstein himself. Her work was highlighted by the American Physical Society’s Focus, New Scientist, Astronomy, and the Laser Interferometer Gravitational-Wave Observatory’s LIGO Magazine.
